: How to fix the 1-3k rpm deadzone for my svt?
I feel like it takes my car like 2 seconds to realize that im flooring it. it first gear, i don't have bog anymore with the tune, but i hardly feel any pickup until i get to about 3k rpms. is this typical for the focus? I realize that in a drag scenario i could leave my car at 3k rpms before i go, but obviously there are scenarios where i cant do that.

The SVT cams are so aggressive that they aren't meant to make power down that low. If you say the bog is gone then there's not much you can do. Peak torque for the SVT doesn't kick in until 4500 whereas it comes on at about 3500 for the Zetec.
yeah i figured, it really doesn't bother me, was just wondering.

his tune has helped hundreds of SVT Focus owners with the bog experienced at low RPMs. not only does the tune help with lowend bog, it helps the entire power band and makes the car more 'drivable'
PM 1turbofocus or email him at firstname.lastname@example.org
he will give you the price.
thanks for reading my entire post and my sig!

thanks for replying with the sarcarsm![thumbd]
in this case, contact Tom and he will take care of ya. you prolly already know of the customer service he provides. take advantage of it and quit complaining.[thumb]

sounds like you want more throttle response. i suggest CFM's 67mm throttle body. i have none of the symptoms you speak of.

I don't have a SVT Focus, but I do have Comp2 cams in my Zetec and a larger Throttle Body did wonders for the low RPM bog I had.

I too have Tom's Tune. I indeed have enjoyed it, but I also experience the lack of response you mention. Good luck, I will see how it goes for you, maybe I will solve this for myself...

if its horridly bad, it could be ur vct solenoid going.

Mine will bog if I go WOT at very low rpm. So, I don't go WOT at very low rpm. The reversion from the big cams messes with the MAF sensor if you open the throttle too far too soon. Some tuners turn the MAF off at low rpm to help this situation. But, too much too soon will always be bad on this engine, I think. Let the revs come up a bit before flooring it and the engine will thank you with better performance.
i am not complaining, i am just wondering if this is a thing with all svts here. i love my tune, i am just wondering if there is something else can increase initial response.
sorry for the sarcasm, just had a long day.

Lightweight flywheel. Easily one of the best things I have done to wake up the car. From the stock 24 (or 26?)lb flywheel to a 12lb Fidanza does wonders. The engine feels so much more responsive especially off the line when spinning a flywheel that weighs half what the stocker weighs. Revs faster and probably just a placebo effect but actually felt like it accelerated faster. Downside is it takes a few to get used to. Taking off is a bit tricky at first cause while it revs up fast, it revs down just as fast.
Alot of people disagree but I still feel like my CAI I had N/A added a good bit of response. It may only gain a few whp over the stock box but IMO the response gained from it was well worth it. Also had to throw another suggestion out for the throttle body.

the 67mm cfm tb and the 12lb flywheel (southbend kit)
are awesome, i switched back to stock tb and it is horrible and i will never drive my car for more than 2 miles on a stock tb.
throw the turd away.
not to mention toms tune is epic.
just get some FI and you wont notice it :P

I have a CAI and 67mm Tb and once I get off the line with said 24lb flywheel it moves quite well. Poor bastard in RSX-S didn't know what hit him.
Have you verified that your IMRC is working?
I'm an owner of a 2003 SVT that I've supercharged (Procharger), and have done other upgrades on (throttle body etc..)..
I love the car and I want to continue increasing its performance.
This thread was interesting because I always felt too that my performance off the line was rather slow with this car and was wondering what upgrades I could get to help that.
I have a LUK Clutch but no other drive train changes outside of OEM parts.
I hear flywheels are a good way to go, but what about a stage 2 or stage 3 clutch. I dont know how much torque my engine is generating at this time, but I have the 67mm throttle body, 42lb injectors and a ProCharger installed.
What cluch kit would be best?

Yup randy at fswerks helped mine! Love the tune

67mm throttle body is what I've been reading should solve this low end stumble.

All in tue tune!
The larger tb will help to.

Hey, I was thinking about either a larger throttle body and a CAI for my svt to give it a little more kick off the line. Since both of those would cost about the same as a light weight flywheel from what I can tell, which would you guys recommend me doing? I don't have a whole lot of money so I wanna get the most out of it.

I'm late to this party, but just a quick comment: While Tom's Tune improves driveability and the SVT experience, you've got to have reasonable expectations. These things aren't quarter-mile tire burners and that lump under the hood was designed by Ford/Cosworth to do its best work between 4,500 - 7,000 RPM. If you don't want to play in that neighborhood, maybe a 5.0 is really what you're looking for?
